Lagoa das Sete Cidades (Lagoon of the Seven Cities) is a twin lake in the crater of a dormant volcano on the island of Sao Miguel; it consists of two small, ecologically different lakes connected by a narrow strait that is crossed by a bridge. The Lagoa das Sete Cidades is the largest body of water in the region and one of the most important freshwater resources in the archipelago.
Although, hydrologically, the Lagoa das Sete Cidades is one lake, it is most often referred to as two separate bodies: Lagoa Verde and Lagoa Azul, the Green Lake and the Blue Lake (respectively). They are so named because each side of the lake reflects the sunlight in different colors.
